CAVERO SANCHEZ, Marcelo Alvaro; BLANCO GUZMAN, Elsa María  e  RIOS, Cesar Giovanni. Evaluation of the environmen tal impact that the burning in the sugar cañe cultivations cuse in BERMEJO. Rev. Vent. Cient. [online]. 2013, vol.1, n.6, pp. 50-59. ISSN 2305-6010.

The burning is that are originated in the sugar cañe cultivations In the town of Bermejo cause severe envlron mental Impacts In that senss, thte research was developed to guide the characterization of the Impacts that burning causes In the physical-chemical properties of the solí, and the quantity of blomass decreased by hectare. Thls research followed a comblnatbn of methodologjes. In the case of the óiganle matter. Ir was calcubted uslng the Walkley and back method, Tho nitrogen using the KJedahl method, refering to the phosphorus it was determlned using the Olsen method, the quantlty of blomass was calculated using mathematical formulas. The most out standing results are the elimination of organlc matter dúo 10 the bumings, causing the other chemical elements of the solí suffer alterations like: the Increment of nitrogen In a temporary way, the phosphoms suffers a volátil trafican as well as the potasslum. When these changes In the chemlcal part exlst, the physbal propertles are also changed. Acompact fiattenlng of the ground exlsts dueto the apparent high density and the llttle porous space existlng hinderlng the Infiltratlon of the water In the ground, harming the sugar cañe production enormously and reaching a fow yield of blomass per hectare.
